Soliton solutions of perturbed NLSE-CQ model in polarization-preserving fibers with cubic–quintic–septic–nonic nonlinearities

Optical solitons for the dispersive concatenation model with power law of self-phase modulation: undetermined coefficients

“…The first type of waveform to be studied is the bright soliton, whose waveform has typically a structure of the form [30][31][32][33][34][35],…”

“…where clearly, and the parameter A, Here, the resulting parameter B is given by where corresponding constraints are assumed to be valid. Thus, the single dark soliton solution for concatenation model ( 1) is (34) where the free parameter A on (32), and the wave number on (30) are expressed in terms of the free parameter B, given in a simplified form on (34). The speed was retrieved on (5).…”

Optical dromions with polarization–mode dispersion having parabolic law of self–phase modulation with multiplicative white noise

“…The refractive index change is taken in the form of parabolic law of nonlinearity [40][41][42][43][44][45][46][47][48][49]. Additionally, in order to give a flavorful taste from a practical standpoint, the effect of stochasticity, in the form of white noise, is also included along both components of the model with PMD [50][51][52][53][54][55][56][57][58][59]. This is the governing model that will be addressed in order to analytically recover the mathematical structure of the dromions and their classifications will also be carried out.…”
